With alsa-cvs (updated today), I have some problems with a RME HDSP card (PCI card). I want it to sync on incoming signal, so I have set the sample clock source to "AutoSync". I have a 44.1kHz input signal on ADAT2, and the driver says "Sync" on ADAT2, AutoSync Frequency 44100. Still, the card runs in Master at 48kHz. Should that be possible even?
When playing around with the settings using hdspconf (changing sample clock source and pref sync ref settings) I sometimes succeed in getting the System Clock to slave at the given input frequency, but only sometimes. I have not really found a pattern how to switch the settings in order to get it to lock. Am I doing something wrong, or is the driver doing something wrong? It is not impossible that there is some clock loop in the system (although I doubt it), I am debugging a system a quarter of a globe away through ssh, and I don't know for sure how all the cables are connected. /Anders Torger ------ volver1:~# cat /proc/asound/card0/hdsp RME Hammerfall HDSP 9652 (Card #1) Buffers: capture dec00000 playback de800000 IRQ: 20 Registers bus: 0xec000000 VM: 0xe0034000 Control register: 0x10160ce Control2 register: 0x0 Status register: 0x2020004 Status2 register: 0xffff8141 FIFO status: 0 MIDI1 Output status: 0xffffff00 MIDI1 Input status: 0xffffff00 MIDI2 Output status: 0xffffff00 MIDI2 Input status: 0xffffff00 Buffer Size (Latency): 8192 samples (2 periods of 32768 bytes) Hardware pointer (frames): 0 Passthru: no Line out: on Firmware version: 1 Sample Clock Source: AutoSync Preferred Sync Reference: ADAT Sync AutoSync Reference: ADAT2 AutoSync Frequency: 44100 System Clock Mode: Master System Clock Frequency: 48000 IEC958 input: Coaxial IEC958 output: Coaxial only IEC958 quality: Consumer IEC958 emphasis: off IEC958 NonAudio: off IEC958 sample rate: Error flag set ADAT1: No Lock ADAT2: Sync ADAT3: No Lock SPDIF: No Lock Word Clock: No Lock ADAT Sync: No Lock ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
